Central Nervous System

The vital centers for the control of visceral activities such as heart rate, breathing, blood pressure, swallowing, and vomiting are located in the:

• hypothalamus

• pons

• cerebrum

• midbrain

• medulla oblongata

Cerebrospinal fluid circulates through all of the following except:

• corpus callosum

• lateral ventricles

• fourth ventricle

• cerebral aqueduct

• subarachnoid space

Sally has a brain injury; she knows what she wants to say but canʹt vocalize the words. The part of her brain that deals with the ability to speak is the:

The cerebrospinal fluid:

• enters the four ventricles after filling and circulating through the subarachnoid space

• is continually formed mostly by the ependymal cells of the choroid plexuses

• is identical in composition to whole blood

• is secreted by the arachnoid villi

The term central nervous system refers to the:
